Struct SectionDescriptor 

#[repr(C)]
pub struct SectionDescriptor {
    pub section_type: u8,
    pub alignment_tier: u8,
    pub reserved16: u16,
    pub byte_offset: u32,
    pub byte_length: u32,

    pub crc32c: u32,
}

One row of the section table — a self-describing section descriptor.

Layout: 24 bytes, repr(C), naturally aligned, no padding.

offset  size  field
0       1     section_type     (SectionType u8)
1       1     alignment_tier   (AlignmentTier u8)
2       2     reserved16       (must be zero)
4       4     byte_offset      (from file start)
8       4     byte_length      (payload length in bytes)
12      4     stride           (bytes per element for AoS sections; 0 = non-strided)
16      4     element_count    (for array sections; 0 = non-array)
20      4     crc32c           (CRC-32C over the payload bytes)

Fields

Implementations

impl SectionDescriptor

pub fn tier(&self) -> Option<AlignmentTier>

The alignment tier as a typed enum (or None if the raw byte is undefined — the reader rejects this).

pub fn typ(&self) -> Option<SectionType>

The section type as a typed enum (or None if undefined).

Trait Implementations

impl Clone for SectionDescriptor

fn clone(&self) -> SectionDescriptor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SectionDescriptor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SectionDescriptor

fn eq(&self, other: &SectionDescriptor) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Zeroable for SectionDescriptor

fn zeroed() -> Self

Calls zeroed.

impl Copy for SectionDescriptor

impl Eq for SectionDescriptor

impl Pod for SectionDescriptor

impl StructuralPartialEq for SectionDescriptor
